结合工程路段土样进行室内试验,测定南阳膨胀土物理力学特性,并进行颗粒分析,进一步对土样进行击实试验,发现该地膨胀土与一般黏性土相异的击实特性,南阳的膨胀土击实曲线呈双峰型,与工程中发现的大多数塑限小于30%的土体的击实特性相符。
The physical and mechanical characteristics of the expansive soil in Nanyang were determined by indoor test with the soil samples of the engineering road sections. The particle analysis was conducted to further verify the compaction characteristics of the expansive soil and the general cohesive soil in Nanyang Compacted expansive soil compaction curve was bimodal, consistent with the compaction characteristics of most of the soil found in engineering less than 30% plasticity.
